Description

Water inlet valve for flush water tank using ceramic chip TECHNICAL FIELD

The invention relates to a water inlet valve of a flush water tank in a bathroom. Background technique

At present, the water inlet valves used in flush water tanks use rubber seals to block the water outlet to shut off the flow of water. The rubber seals are not abrasion-resistant and often leak due to erosion by the water flow. Often the water inlet valve Other components can still be used normally, but the rubber seal is worn and damaged and cannot be repaired. One of the leaks increases the user's water cost, and the other is contrary to the current vigorously promoting water conservation policy. Furthermore, once a leak occurs, it must be replaced. The entire water inlet valve device causes an extra burden on the user. Summary of the Invention

In view of this, how to provide a wear-resistant material and structure to increase the service life of frictional rotating parts, make it as close as possible to the service life of other supporting parts, and greatly extend the service life of the water inlet valve. Motivation for innovation.

The designer of the present invention, with years of practical experience in research, production, and processing of various types of bathroom and various device technologies, based on repeated research and demonstration, made a completely new design and construction, which ultimately resulted in the invention.

The purpose of the present invention is to overcome the abrasion and leakage of the water inlet valve of the existing flush water tank, and use wear-resistant ceramic chips to equip it.

The technical solution of the present invention is composed of a valve seat, a seal, a valve cover, a floating ball, and a connecting rod, and is characterized in that a ceramic chip is used as a seal for shutting off water flow in the valve.

The ceramic chip of the present invention is composed of a ceramic core fixed piece and a ceramic core moving piece which are closely fitted with each other. The ceramic core moving piece is connected to the connecting rod. The ceramic core fixed piece has a fixed plate water inlet, and the ceramic core moving piece can cover the ceramic core. The water inlet on the fixed piece; the ceramic core fixed piece has a fixed piece water inlet, the ceramic core moving piece has a moving piece water outlet; one end of the connecting rod is connected to the floating ball, and a weight body is connected to the floating ball end, or the floating ball is provided with two At the open end, one middle opening is in the middle of the floating ball, and the other bottom opening is provided at the bottom of the floating ball. The opening in the middle of the floating ball is a threaded interface, which is connected to the connecting rod by threads. The invention utilizes the characteristics of high hardness, abrasion resistance and no aging of the ceramic chip, and uses the ceramic chip as a seal to greatly improve the overall service life of the water inlet valve.

The inlet of the water inlet designed by the present invention mainly uses a ceramic chip to seal off the water flow.

The ceramic chip of the present invention is composed of a ceramic core fixing piece 1 and a ceramic core moving piece 2 which are closely fitted together. The ceramic core fixing piece 1 is fastened to the valve seat 6 by a sealing rubber pad 5. The ceramic core moving piece 2 can be The valve seat 6 and the valve cover 11 rotate, as shown in FIG. 1, it can be seen that the ceramic core moving piece 2 is connected to one end of the connecting rod 9; the ceramic core fixed piece 1 has a fixed piece water inlet 3, and the ceramic core moving piece 2 can cover the ceramic core. Water inlet 3 on the fixed piece; or ceramic core fixed piece 1 has fixed piece water inlet 3, ceramic core moving piece 2 has moving piece water outlet 4; one end of the connecting rod 9 is connected to the floating ball 8, and a weight body is provided at the end of the connecting floating ball 7, or the floating ball 8 is provided with two open ends, one of the middle opening 11 is in the middle of the floating ball, and the other bottom opening 12 is provided at the bottom of the floating ball; the opening in the middle of the floating ball is a threaded interface 13, which is just through the thread and the connecting rod connection. When the water level changes, as the floating ball 8 rises and falls, the connecting rod 9 can drive the ceramic core moving piece 2 to rotate.

The specific actual working process of the water inlet valve of the present invention in the flush water tank is as follows:

When the flushing water tank is empty, the float 8 is at the low water level of the water tank. At this time, the fixed plate water inlet 3 on the ceramic core fixed plate 1 and the ceramic core moving plate 2 are staggered, or the fixed position on the ceramic core fixed plate 1 Tablet inlet 3 with The moving blade water outlet 4 on the ceramic core moving blade 2 is correspondingly connected. At this time, water flows from the water inlet pipe 10 through the fixed blade water inlet 3 and the moving blade water outlet 4 to the water tank, and when the water level gradually rises, the floating ball 8 follows Ascending, the connecting rod 9 is driven to rotate, and the ceramic core moving piece 2 is also rotated. When the water rises to a predetermined height, the ceramic core moving piece 2 completely covers the fixed plate water inlet 3 on the ceramic core fixing piece 1, or the ceramic core. The moving piece water outlet 4 on the moving piece 2 and the fixing piece water inlet 3 on the ceramic core fixing piece 1 are staggered and do not communicate with each other. The water inlet is stopped, and the water inlet valve is closed.

Since the ceramic core fixing piece 1 and the ceramic core moving piece 2 are closely fitted, there is a certain resistance during relative rotation. Therefore, when the floating ball is a sealed body, the floating ball itself is generally made of plastic, and its gravity may not be sufficient to overcome The frictional resistance between the ceramic core fixing piece 1 and the ceramic core moving piece 2, therefore, a weight 7 needs to be added so that when the water level drops, the weight drives the connecting rod to rotate so that water can flow into the water tank; another very clever technical solution No counterweight is used. There are two open ends in the floating ball 8, one middle opening 11 is in the middle of the floating ball, and the other bottom opening 12 is set at the bottom of the floating ball. The bottom opening 12 has a smaller opening. When the water level drops rapidly Since the floating ball has two open ends, the bottom opening is small, and water flows out slowly from the bottom opening of the floating ball, the gravity generated by the water remaining in the floating ball causes the floating ball to drive the connecting rod to rotate, and when the water level rises Water will enter the floating ball, and when the level of the floating ball exceeds the opening 11 in the middle of the floating ball, both openings of the floating ball are sealed by water. Make float Still able to float on water; float is a central opening threaded interface 13, just by screwing the link.

When the water level of the flush water tank drops due to flushing and discharging, and the float stops at the low level of the water tank, it returns to the state of the water in the water tank and the water inlet valve is opened. This is the flush water control valve using ceramic chips. Works.

Since the flush water tank is assembled with a wear-resistant ceramic chip, the wear resistance of the ceramic chip greatly prolongs the service life of the worn parts, and it doubles the life of the entire inlet valve.

In summary, the present invention can make use of the selection of wear-resistant materials and simple structural design, so that the product of the present invention can greatly increase the service life of vulnerable parts, make the service life of each part approach, and make the product reliable and overall. The service life has also been greatly improved. Obviously, the present invention is a new, advanced and practical new design. The above are the specific embodiments of the present invention and the technical principles used. If the equivalent changes made according to the concept of the present invention, the resulting functional effects do not exceed the spirit covered by the description and drawings It should be explained within the scope of the present invention.
